<p><P>PROBLEM TO BE SOLVED: To provide a method for supplying a clock signal which is not affected by any temperature change or power supply voltage fluctuation in a circuit for performing access to a memory. <P>SOLUTION: This memory circuit is provided with a delay circuit for generating a delay clock signal by delaying a reference clock signal, a temperature detecting circuit and a voltage detecting circuit. The temperature detecting circuit detects the temperature of the periphery of the circuit, and the voltage detecting circuit detects the power supply voltage of the circuit, and the delay circuit decides the delay amount of the delay clock signal based on either the temperature data detected by the temperature detecting circuit or the voltage detected by the voltage detecting circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
